An asymmetric model routes at the ingress leaf toward a remote MAC using the L2 VNI, while the egress primarily bridges. How does that differ from symmetric IRB?
Select an answer to reveal the explanation.
Short Explanation
Asymmetric is a one-way translator at the entrance and a simple bridge at the exit. Symmetric puts routing on both ends with the same L3 VNI playbook. They are not the same thing with different numbers.
Full Explanation
In asymmetric IRB, the ingress VTEP performs routing and typically sends toward the destination MAC over the L2 VNI, while the egress bridges. Symmetric IRB has both VTEPs participate in routing with consistent L3 VNI/VRF encapsulation. The models are not identical, and neither implies MPLS-underlay mandates or abandoning EVPN.
